We’ve been using the DexCom CGM for a few months. The adhesive seems to stick well, but as we push each sensor to its limit the issue sometimes becomes the adhesive, not the sensor itself.
I have heard several people with diabetes (PWD’s) and parents say they use Opsite FlexiFix. It comes in a roll and you can cut the length you need. You can also cut out a hole for the sensor.
Prices of this adhesive vary greatly. Amazon was NOT the best price I found. Some sites were much cheaper, but shipping was expensive. In the end I decided to order from American Diabetes Supply.
(And here’s a tip for online shopping: I ALWAYS sign in to Ebates before I make any online purchase. You can earn cash back rebates from a ton of online retailers such as Lands’ End, Disney Store, and even American Diabetes Supply. I used it when I did all my online holiday shopping last year and got a check back for about $30! If you don’t already use EBATES, you can sign up here.*)
So, back to Opsite Flexifix. The first couple of times I used it I had a tangled mess and stuck my fingers together. A few people gave me tips and using those, plus my own experience, I now have a system that works pretty well. Because everything diabetes has to be complicated, right?!
I eyeball and cut a piece that will extend past the DexCom adhesive.
I use an old sensor to trace a hole for the middle.
I was perplexed by how to cut out that center hole without breaking out the craft knife. I had the idea to fold it over and cut it out. Works much easier for me.
Here’s where I used to get tangled. The first few times I took off both halves of the adhesive that said to remove first. Now I just take off the one strip of it so I can get it in place.
Then I remove the second half of the white “remove first” backing and smooth it down.
Lastly I peel off the green grid layer. Et voila!
When we were using the Medtronic CGM we would cover the entire thing with Tegaderm because you had to keep the clam shell shaped transmitter in place. With the DexCom you don’t have to use a layer of adhesive until well into it’s life cycle. This isn’t medical advice (none of this ever is!) but some people wear a DexCom sensor two or three times as long as it is FDA approved for.
And something I learned at Friends For Life in the session with the rep from the FDA is that a device is medically approved for a certain length of time based on the study that the company submitted. The DexCom isn’t approved for kids only because they didn’t do a pediatric study and submit it to the FDA. They are currently doing a pediatric study on the next gen DexCom G4 Platinum system. Yay! The DexCom sensor is approved for 7 days and the Medtronic sensor is approved for 3 days because that’s what they submitted to the FDA. The sensors in theory could work longer, but they aren’t technically approved for longer.
And I’m not telling what day we were on when I slapped that Opsite Flexifix on Q!
